FEEDING DEVICE FOR THBESHING-MACHINES.

Specification of Letters Patent.

Application filed January 19, 1918. Serial No. 212,575.

To all whom it may concern Be it known that I, JOHN H. CRUMB, a citizen of the United States, residing at Lawrence, in the county of Douglas and State of Kansas, have invented a certain new and useful Improvement in Feeding Devices for Threshing-Machines, of which the following is a specification.

My invention relates to improvements in feeding devices for threshing machines.

It relates particularly to feed regulators for threshing machines.

One of the objects of my invention is to provide a feed regulator which is adapted to be attached to the trough of a grain feeder or bundle carrier, which will automatically temporarily restrain and hold back the feed ing of surplus grain or bundles, so as to make the feeding of the grain uniform and to avoid liability of choking down the machine.

A further object of my invention is to provide a novel feed regulator, which may be easily and quickly adjusted so as to enable it to feed different amounts of grain.

Still another. object of my invention is to provide a feed regulator which does not interfere with and is independent in operation from the regular feeding mechanism or other running parts of the machine. 1

My invention provides further a feed regulator which is simple in construction, economical to manufacture, which is durable and not liable to get out of order, and which is reliable in operation.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which 1llustrate the preferred embodiment of my lnvention 7 Figure 1 is a vertical sectional view on the line 11 of Fig. 2, showing my improved feed regulator attached to the bundle carrier of an ordinary threshing machine, a portion of which is shown partly in side elevation and partly in vertical section,

Fig. 2 is a vertical sectional view on the line 22 of Fig. 1.

Fig. 8 is a horizontal sectional view line 33 of Fig. 1.

Fig. 4 is a perspective view of my improved feed regulator.

on the Fig. 5 is an enlarged vertical sectional view of the lower end of one of the supporting standards of the frame of the regulator.

Fig. 6 is a side elevation of one of the plates which support the frame.

Similar reference characters designate similar parts in the different views.

The feed regulator is provided with a vertical frame comprising two channel standards 1, the upper ends of which are rigidly secured to a transverse bar 2.

, 3 designates two plates, one of which is shownin Fig. 6, which are adapted to be respectively secured to the opposite inner walls.

of the trough 4 of an ordinary bundle carrier or grain feeder, which is provided with the usual conveyer belt 5, which carries the grain upwardly to the rotary band cutter 6, which is rotatably mounted in the usualmanner at the forward end of the body 7 of the thresher machine.

The lower ends of the standards 1 are bi furcated and have secured between the arms of said bifurcations the supporting plates 3. Respectively extending through the plates 3 and the adjacent arms of the members l'are two bolts 8 provided with nuts 9, by means of which the bifurcated ends of the standards 1 may be securely clamped to the plates 3. Inorder that the plates 3 may be held from turning in the standards 1, the inner sides of the arms of the latter may be provided with radial corrugations 10, Fig. 5, which are adapted to interlock with similar corrugations 11 provided at opposite sides of each of the plates 3. The plates 3 are provided each with bolt holes 12, through which extend bolts 13, mounted in the sides of the trough 4. Vertically slidable in the channels of the standards 1 is an inverted U-shaped support comprising a plate 14, having two depending arms 14, to which are secured, adjacent to its opposite ends respectively, two vertical racks 15, with which respectively mesh two pinions which are rigidly secured to a shaft 17, which is rotatably mounted in bearings 18, which are secured to the channel standards 1 respectivelv.

Two parallel transverse bars 19 and 20 are pivoted at their ends in the depending arms 14 of the support 14. Respectively rigidly Patented Apr. 8, 1919.

' secured to the bars 19 and 20 are two pinions 21 and 22, which mesh with each other.

Rigidly-secured to the bar 19 is a trans.-

verse depending member 23,. which is adapted to be disposed above the conveyerbelt 5, in the trough 4, and which isadaptedtobe swung to the left, as viewed in Fig; l by surplus grain which is being carried; upwardly in the trough 4 by the be1t5toward the band cutters 6. 7

'Respectively rigidly secured to the bars 19 and 20 are two U-shaped retardinge or re-i straining devices 24 and 25, which are disposed at opposite sides of the frame 1, and

the transverse portions of each of which are provided with downwardly extendingteeth 26- which are adapted to engage'and hold back surplus grain which strikes againstand swings-the member 23. v V

VVhenthe bundles'of grain, or loose straw in passing up the chute 4strike' against the depending member 23, the latter will be swung to the left, as viewed in Fig. -'1, thusswinging both of the restraining'dev'ices 24- a'nd25 downwardly, as for example to the position shown in dotted lines in Fig.1, in

I 'which position, the teeth 26 will engage and and which is below the surplus grain, has

ends of which are hold the surplus bundle or straw from moving toward the band cutters 6. When the grain which is underneath the-member 23,

passed from under the surplus grain, the latter will fall upon the belt 5 and will beucar -ried onwardly to the band cutters and-into the machine in the usual manner.

7 For retracting the member 23 and the devices 24 and 25 to the position shown in solid lines in Figs. 1 and 4, there are provided two coil springs 27, one set of ends of which are secured to the device 25, and the other-set of shaft 17. I

By turning the crankshaft 17 in the proper directions, the support 14, together with thep-arts carried thereby, may bevertically adjusted to positions in which themember 23 will be at the-proper distance above thebelt 5 in order to accomplish the purpose desired.

held from movingdownwardly by releasable means, which may comprise a pawl 28, Figs. 2 and 4, which is pivoted to one of the channel standards l,'and which'is adapted to engage the adjacent pinion 16.

To prevent grain being thrown down upon the restraining device 24, a'. curved forward'ly and downwardly extending. shield 29 is. secured to and movable with thesupport 14.

When the feed regulator isadjusted sons to permitgrainto thedepth of one ,bundle'to pass under the member 23, if two bundles happen to be superposed one on the other,

fastened to r the crank After the proper adjust ment has been given to the support 14, it is the upper bundle will strike the depending member 23 and will force it from the verticalposition toward the position shown in dottedlines in Fig. 1,. uponwhich the: dc-

vices24 and 25 will be swung downwardly by means. of'the bars. 19 and 20 and pinions 21"and 22,causing the teeth 26 to engagethe uppermostzbundle so as to hold it until the conveyer belt 5 has carried the lower bundle frombeneath the upper bundle, upon which, 7

the latter will fall upon the belt5and*out' ofeiengagement.iwith;the member 23 and devices 24 and 25, uponwhich the springs 27 will restore the parts tothe:normal-position shown I in solid lines in- Figs? land 4.

The members- 3 being hinged to the chan-' nel standards loffthe frame, may beswung to any *angle to corresp ond" with the "angles of thesides of the :trough 4fto whichithe feed regulator is: to bis-attached;

When it is desired to elevatethe mem-v ber 23', the crank shaft 17 is turnedcounterclockwise, as viewed in Figs. 3 and 4, thus causing the :pinions16 to--lift"the}ra'cks f1 5,
